背景技术Background technique
随着成像显示技术的发展，对成像的特性要求不断提高。空中成像技术是在光波导透镜的一侧中配置的被投影物中发出的光在光波导透镜里的镜面反射并同时透射该光波导透镜平面，从而使该被投影物的镜影像在该光波导透镜的另外一侧的空中成像为实像，空中成像技术通过在空气中形成物品的影像，使得人们无需借助VR眼镜等辅助设备就可以看到物品的影像，给人以强烈的视觉震撼效果，受到越来越多人的关注和追捧。然而，现有的光波导透镜模板用机械加工的方法加工，工艺复杂，加工成本高，光波导透镜模板上的凹槽内壁光泽度很难加工成镜面纳米级。With the development of imaging display technology, the requirements for imaging characteristics are constantly improving. Aerial imaging technology is the specular reflection of the light emitted by the projected object arranged in one side of the optical waveguide lens in the optical waveguide lens and transmits the plane of the optical waveguide lens at the same time, so that the mirror image of the projected object is reflected in the optical waveguide lens. The aerial imaging on the other side of the waveguide lens is a real image. The aerial imaging technology forms the image of the item in the air, so that people can see the image of the item without the aid of VR glasses and other auxiliary equipment, giving people a strong visual shock effect. By more and more people's attention and sought after. However, the existing optical waveguide lens template is processed by a mechanical processing method, which is complicated in process and high in processing cost, and the glossiness of the inner wall of the groove on the optical waveguide lens template is difficult to be processed into a mirror surface nanometer level.
